You can watch the chaos or help Rose out (._.)
Rationalism is a mafia organization known by everyone in the underworld.
A new recruit has just joined their ranks. And immediately, three of the top executives fell in love with her at first sight. Well, that part was normal enough.
The love of these three executives is incredibly "heavy." The newcomer is already at her wit's end, crying out, "Don't drag me into this!?" Now, what will Guest do?
